SECTIONAL RADIATOR. k

' Application'filed May 23,

To all whom it may concern."

Be it known that I, JosEPH A. CONRAD, a citizen of the United States, residing at Beloit, in the county of Rock and-Stateof Wisconsin, have invented certain new and useful Improvements in Sectional Radiators, of whichthe following isaispecification.

This invention relatestofiradiators for use with water-.cooleddnternal combustion engi-nes and .has 'more particular reference to those used on motor vehicles.

The primary object of the present invention is to -proVideMaNneW iand improved radiator especially. designedpto simplify repairing. "The tubes Orv-circulating pipes not. infrequently are bursted asfa resultof freezing, and they are sometimesbroken as the result of accident,sand' in other instances simply by: wear. of thejoints-. Heretofore, ithas been quite diflicult-to--repa1r these tubes by reason of thefact' that the radiation finsflhave 'been soldered-i 0p otherwise secured to the tubes, makingiitdiflicultto repair and to get to 1 the Y point. of leakage especially if it is one of the inner'tubes of the group. I have overcome the 111001)- venience. attendant; upon making these re pairs by the'provisionbf a sectional radiator, that is,wone having removablesections permitting ready access to. the circulating tubes/m 1 My invention also? contemplates theprovision of a sectional radiator. characterized by a tank and tube section, anda removable front casing section" carrying radia: ti'on-hfins disposed when. inoperative position, in front ofsthe circulating tubes. This casing section =is-designed-to. have the out- Ward, appearance of 1 a conventional radiator, but which is-in fact, quicklyremovableto giveready access to .the' tubes and -to- :the uppera-nd lower tanks glt will be mani fest that inasmu'chxas all repairsof, the tanks ortubesare ma'dewhen the front casing section" is removed, the, finish of the latter is i not marred by the solderingorf other repairing operation. In -the preferred embodimenu-aback finsection-is also employed. 3 Another object is to. provide =a-sectio-nal radiator: of the x character 1 described iconst'ructed' i-lIl such simple. and practical 'manner as to' enable production at a "comp aratively lowcost andwhich Wl'lllOB thoroughly practical for the purposesintended. .1

will be appreciated'by those familiar with this art as the invention becomes better understood by reference to the following description, when considered in connection .with the accompanying drawings, in which-- Figure 1 is a perspective view of aflsectional radiator embodying my invention;

iMy invention comprehends, primarily, provision-of a radiator comprising a tank and tube section and a front casing section having radiation fins, and I prefer also to employ a back radiation fin section, these to be'removably associated so that the front casing section and the back'fin' section may be quickly and easily removed from the tank and tube section when it'is necessary to re- P ir leaks in'the'latter. y In the preferred embodiment shown, the tankandtube section is made up of upper and lower tanks 9 and 11 respectively, joined by vertical circulation tubes or pipes 12, preferably elongated transverselyto the path of rest on the frame of a motorvehicle and i to be bolted or otherwise secured thereto.

Additional means, not shown, may be proother cooling liquid enters the tank 9 through pipe hose connection 14 and cir-. culates down through the tubes 12 and thence through the tank and connection 15 in the usual manner, it being manifest that the pipes 14 and 15 are to be connected with the water chamber orjackets of the engine for circulation of the water through the latter. In the preferred'embodiment, radiation fins 20 may be interposed between and soldered or otherwise united to'thetubes 12 for increasing the radiation efliciency', it being noted that by this arrangement of sides, as shown in 'Fig. 6, to facilitate re-- frame structure. Inwthe present instance,

bolt holes are provided through the arms 13 and 22 for the reception of retaining'bolts. The top wall 21 of the "front casing section has an opening 23 for the passage of the upstanding fillermouth orpipe 16, The front wall 18 of said casing has an opening 24' disposed in front of and registering with the circulating tubes 12. This opening-is covered by radiationfins 25 disposed-at the inner side of said front wall I18and .se-' cured thereto so as to occupyia position directly in front of. and incontact with the foremost circulating pipes. Saidradiation fins 25 will be held in contact: with said circulating pipes by the bolts '(nots'hown) which pass through the arms'13'and 22 and clamp the casing and :radiator to. the chassis. The fins thus become conductors and serve to radiate heat from the foremost tubes. It will be manifest that the front casing se'c tion incloses the front, sidesuandtop QfIthe tank and tube section, and by" reas'on'of its design and finish gives the .outward'appearance of an integral radiator structure, whereas the casing section maylbequickly and easily removed from the tank and tube section so as to expose the latter andiper mit repairs of the tubes and tanks to be'made with greater facilityand at less cost than is possible with those integral radiator. con structions in which the tube and radiator fins are rigidly united. i i

I have also provided a back fin section shown in Figs. 5 and 8Lcomposed of a' suitable frame 26 carrying fins 27 and adapted to be removably mounted at the b-ack 'of and'in contact with the rearniost circulating tubes. The upper edge of this frame 26 is retained against displacement by a suitable guidepsuchas an angle iron bar 28, and the lower end is provided with depending brackets 29 adaptedto be secured by bolts 31 to the lower'tank. When in operative position, the. radiation fins on this section will be held in contact with. the rearmost circulation tubes; This back finsection may obviously be easily removed and replaced, and will when in operative position, function as a heatradiating and water-coolingmeans.

It is "believed that the foregoing conveys a clear understanding of the objects prefaced above;an'd whilel have illustrated but a single embodiment, 'it should be understood that considerable change might be made in details of construction without departing fromz--thelspiritand scope of the invention as .efx ressed -in' rtheappended claims: 1 i
